The White House says the Senate Democrats’ new budget is a “concrete plan” that will boost economic growth and shrink deficits.

White House press secretary Jay Carney said the proposal unveiled Wednesday also would make needed investments in education, manufacturing and roads and bridges, and require tough spending cuts that won’t disproportionately affect seniors and the middle class.

The Senate Democratic plan calls for $1 trillion in new tax revenue in the coming decade but would actually increase spending. It would add $4 trillion more to the national debt than an alternative spending plan introduced Tuesday by House Republicans.

Carney had criticized the House GOP plan as having math that doesn’t add up.
